i The Schedule referred to in theseLetters Patent and making part of thesame To all whom 'it may concern:

Be it known thatJ, SILAs R. KENYON, of Greenville, in thecouuty ot'Providence and State oflthde Island, have invented a' new and usefulImprovement in Attaching` Rubber to the Metal Shafts of Rollers, and thefollowing isdeclared to be a correct description thereof;` y I IDiiculty haslbeen experienced iu connecting rubber rollers to theirmetal shafts, so that fthe` rollers @cannot become `loose orfdetached.Various' plans have been adopted for effecting this object, espe-`cially iu connection with the wringing-machine rollers.' v i Myinvention is adapted `to rubber rollers ygenerallyywhether such rollersare employed'iu wringingmachines or in corn-basking machines, such asbefore patentedv by me, or in'anyi other kind of machinery.

I bore, or form `several holes through the shaft i transversely of 'thesame, and at suitable distances apart, Aalong suchroll'er. -Into theseholesl introduce pieccsof India'rubber, of a length toproject slightlyfrom the surface. The` ends of'these pieces of rubber, shown at Wein:accompanying' drawing, are to becoated with India-rubber cement.ljprefer also that the snrfaceof the sadroller should be coated inthesame'manuer. j i

` Around the meta-l shaft thus prepared, sheet India i rubber isto bewound, and then compressed into a metal mold, having a roughened 0rcorrugated surface, so that the India rubber or gum is pressed firmlyupon the shaft and the ends of the rubber pieces a a. A

4The roller is to be subjected to heat or vulcanized, while in the mold,so as to cause all the gum to become as vone continuous mass, hence theiblocks Aor pieces a a becomev dowels tohold the rubber cylinder b firmlyupon the shaft c, and it is not possible to loosen ythe roller untilthese dowels are cut olf, so that for all practical purposes the rubberroller and shaft become as one. y In the drawing- Figurel is alongitudinal section of the roller, and Figure?, a cross-section. Iclaim as my invention- 1. The rubbendowels, passing into and throughholes in the shaft, to connect the rubber cylinder to said shaft. 2. Arubber roller, having a.` corrugated surface, produced by the interiorof Vthe. mold,'in which the .same is vulcanized.
